Triple Quotes? How do I delimit a databound Javascript string parameter in ASP.NET?

Question!

How do I delimit a Javascript databound string parameter in an anchor OnClick event?

  • I have an anchor tag in an ASP.NET Repeater control.
  • The OnClick event of the anchor contains a call to a Javascript function.
  • The Javascript function takes a string for its input parameter.
  • The string parameter is populated with a databound value from the Repeater.

I need the "double quotes" for the Container.DataItem.
I need the 'single quotes' for the OnClick.

And I still need one more delimiter (triple quotes?) for the input string parameter of the Javascript function call.

Since I can't use 'single quotes' again, how do I ensure the Javascript function knows the input parameter is a string and not an integer?

Without the extra quotes around the input string parameter, the Javascript function thinks I'm passing in an integer.

Cheers in advance for any knowledge you can drop.

The anchor:

<a id="aShowHide" onclick='ToggleDisplay(<%# DataBinder.Eval(Container.DataItem, "JobCode") %>);' >Show/Hide</a>    

and here is the Javascript:

<script language="JavaScript" type="text/javascript">
/* Shows/Hides the Jobs Div */
  function ToggleDisplay(jobCode)
  {
  /* Each div has it's ID set dynamically ('d' plus the JobCode) */
    var elem = document.getElementById('d' + jobCode);

    if (elem) 
    {
      if (elem.style.display != 'block') 
      {
        elem.style.display = 'block';
        elem.style.visibility = 'visible';
      } 
      else
      {
        elem.style.display = 'none';
        elem.style.visibility = 'hidden';
      }
    }
  }
</script>

I had recently similar problem and the only way to solve it was to use plain old HTML codes for single (&#39;) and double quotes (&#34;).

Source code was total mess of course but it worked.

Try

<a id="aShowHide" onclick='ToggleDisplay(&#34;<%# DataBinder.Eval(Container.DataItem, "JobCode") %>&#34;);'>Show/Hide</a>

or

<a id="aShowHide" onclick='ToggleDisplay(&#39;<%# DataBinder.Eval(Container.DataItem, "JobCode") %>&#39;);'>Show/Hide</a>
